Screaming Frog vs Lumar

This comparison usually comes up when a site outgrows a desktop crawler. Screaming Frog runs on your machine, so crawl size depends on your memory and storage. Lumar (formerly Deepcrawl) is cloud-only, built for large sites and teams, with monitoring, release QA and accessibility reporting.

At the time of writing (September 2026), Screaming Frog is £199 per user per year. Lumar publishes no prices; you request a quote. Its crawler page claims speeds up to 450 URLs per second non-rendered and 350 rendered.

Where LaunchRanked fits

Disclosure: LaunchRanked is our product. Where we list it, we say so, and we place it under the use case it fits rather than at the top by default. Everything else here is from the vendors’ own sites or our research, and we say where they’re better.

We don't sell a crawler. Both tools find technical issues; neither fixes them. And if you're weighing Lumar, your site is probably bigger than the ones we work with.

If the audit keeps finding problems nobody has time to fix, Done-for-you (from $999/mo) includes technical SEO by hand. Autopilot ($49/mo, early access) handles content and Search Console title rewrites, not site code.

Frequently asked questions

Is Lumar the same as Deepcrawl?

Yes. deepcrawl.com redirects to lumar.io, and Lumar's site says Deepcrawl is now Lumar.

How big a site can Screaming Frog crawl?

Its pricing page says the maximum depends on allocated memory and storage. Very large sites usually need database storage mode and a powerful machine, or a cloud crawler.

Does Lumar have a free trial?

We didn't find one at the time of writing (September 2026); its site offers demos and quotes.
